The unwanted material, or tailings, is returned to the mined areas to help return it to its original form. Tailings deposit areas are contoured to recreate the original land forms. Marram grass and radiata pine trees are planted to stabilise deposits and minimise wind-blown sand. The tailings consist of river water containing clays and sands.
